Scale

Collection of pitches in ascending and descending order

Diatonic

Across the tones

Diatonic scale

a scale of mixed half and whole steps each having a role

Chromatic

A nondiatonic scale consisting entirely of hald-step intevals.

Major scale

Scale of 7 different pitch classes with whole steps separating adjacent tones except for half steps between the 3rd and 4th and the 7th and 8th degrees. (WWHWWWH)

Pure/natural minor

7 different pitches with whole steps separating adjacent tones except for half steps between the 2nd and 3rd and the 5th and 6th degrees (WHWWHWW)

Harmonic minor

Natural minor scale with a raised 7th degree

Melodic minor

Natural minor scale with raised 6th and 7th degrees on the ascending and a natural minor scale on the descending

Key signature

Tonal system based on the major and minor scales

Relative scales

Major and minor scales with the same key

How to find relative scales

finding relative minor scales

6th degree of the major scale becomes the minors tonic

Finding relative major scales

The third degree of the minor scale becomes the majors tonic

Parallel scales

Major and minor scales with the same tonic

circle of fifths

A tool to help visualize relationships between major and minor scales

Major scale tonics on the outer scale

Key signatures within the circle

relative minors within the inner circle

Tonality

An original system of tones in which one tone becomes the central point to which the remaining tones are related

Pentatonic scale

A five tone scale

Whole tone scale

six tones all seperated by whole steps

Octatonic/diminished scale

eight notes that are separated by alternating half and whole steps

Ionian

1st Mode

Dorian

2nd mode

Phrygian

3rd mode

Lydian

4th mode

mixolydian

5th mode

aolian

6th mode

Locrian

7th mode

Solfeggio

Vocal exercises sung to a vowel, syllables, or words that indicate scale degrees

Pitch inventory/collection

List of tones used in a composition or section thereof

Pitch class

All notes of the same name regardless of octave

Transposition

Major scale pattern is duplicated at any pitch

Non-diatonic scale

A scale that does not observe the interval sequence of the diatonic or pentatonic. Many don’t have an identifiable tonic

Names of each scale degree for minor scales

tonic, supertonic, mediant, subdominant, dominant, submediant, subtonic
